Specification forming part of Letters Patent No. i ,4il7, dated October9, 1866.

To all whom it may concern:

Be it known that I, ALLEN HUsroN, of Cincinnati, in the count v ofHamilton and State of Ohio, have invented a certain new and usefulImprovement in Hubs; and 1 do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings,- making a part ofthis spccification, in which Figure 1 is a perspective view of a hubcontaining my improvement. Fig. 2 is a sectional view of the lmb,showing the arrangement of the parts. Fig. 3 is a perspective view of aportion of the parts of which my improved hub is composed.

My improvementcons sts in making a me tallic hub in two parts, one ofwhich is cast around or within the other, so that they may beinseparably connected, while the outer portion is tap-able of motionabout the inner portion.

In the drawings, A represents the inner portion of the hub, through thesquare, holein the center of which a stationary axle passes. Thisportion, therefore, does not revolve.

B represents the outer portion of the hub, containing the sockets forthe spokes. This portion revolves freely about the part A, and carrieswith it the spokes, follies, and tire.

The inner portion, A, is cast with a rib, D, upon it, which rib passesaround the center of the periphery. The periphery of the rim is grooved,as shown at X, for the purpose of oiling the joint.

The outer portion, 13, is cast with a groove, E, in the center of theinner circumference. This groove is of a size suflic'ient to receive therib I), so that the two pieces, while freely revolving one about orwithin the other, shall be inseparable. Oil is introduced through theaperture H.

This hub is made by casting the inner por tion, A, and then casting theouter portion, B, around it, the circumference of the part A form in gpart of the mold 5 or the operation may be reversed, B being cast firstand used as a mold for A. The sand in the groove X of the rib D isremoved through the oil-hole E.

It is obvious that the rib may be upon the part B a1ul"'theilange uponthe part A, or vice versa, as described. 4

What I claim as my invention, and desire to secure by Letters Patent,is-

Casting a hub in two concentric parts, one about or within the other, sothat while the parts are inseparable each may revolve freely in relationto the other, substantially as described.
